RAIL-JOINT SUPPORT.-

Application filed January 16, 1929. Serial No. 332,997.

The invention relates to means for connecting the adjacent ends of railroad rails and supporting them in position, and has particular reference to means for supporting the switch points of railway switches in relationship to the fixed rails at the switch, and has for its object the provision of a sup port including a chair having means to securely hold the fixed rail member of a switch in a fixed position and providing means whereby the switch point rail is held in proper relationship to the fixed rail with means whereby the switch point rail is pivthe chair.

A further object of the invention is the provision of means for joining the two adrails whereby one of said rails is arranged to pivot relatively to the other rail, said means including a chair for supporting the adjacent ends of the rails and having means to clamp the two sides of the fixed rail,and provided with resilient means to clamp'the movable rail permitting pivoting of the'rail within the chair.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings, in which- Figure 1 is fragmental plan view of a railroad track showing a switch structure and the improved means for supporting the adjacent ends of the fixed rails and switch points,

Figure 2 is a top plan view of one of the rail supports,

Figure 3 is an end view showing the rail in section,

Figure 4 is a horizontal sectional view,

Figures 5 and 6 are transverse sectional views on planes indicated at 55 and 6-6, respectively, in Figure 2, and

Figure 7 is a side view in elevation of the wedge clamping member.

In the drawings similar reference characters are used to designate corresponding parts in all of the views.

In Figure 1 is shown a fragment of a railroad track in which the main line rails are designated A and A respectively, andB and B designate turnouts or rails leading to a siding or switch. The switch points are designated G, in alinement with the rail B, and C that is alined with the rail A, said switch points being connected to a slide bar D by means of the clamps E. Means for supporting the adjacent ends of the rails B and C, A, C, are designated G and comprise ohairs, each having a base portion 1 thatis recessed as shown at 2 to receive one of the rails such as A, one wall of the recess 2 designated 3 engaging and supporting one side of the rail. The adjacent-end of the rail C is also engaged by a wall 3 when in one of its adjusted positions The opposite sides of the rails are engaged by a clamping member that is formed in two sections, designated 4 and 5 respectively, and said sections are provided with recesses 6 thatengage studs 7, on corresponding sides of the rail or any otherv means may be provided for engaging the rails with the members 4 and 5. 8 is a hoolrmember thatcis pivotally mounted in a recess 9 of section 5 onjain .10, andadapted to engage a pin 11 in the member 4, said member 4 being also recessed as shown at 12 to receive the bill of the hook and permit engagement thereof with the pin 11to hold the members 4 and 5 pivotally connected as shown best in Figure4. Walli13 of the recess 2 is provided with a groove 14, and the clamping sections 4 and 5" are grooved as shown at 15 to receive tongues 16 and 17, respectively, on a wedge member 18, the recess 2 being tapered to engage the wedge member 18. ledge member 18 has a portion 19 that engages the section 4 of the clamping member, and is recessed as shown at 20 opposite to the clamping member 5 and has pivotally secured in said recess 20 a block 21. said block being pivoted by means of a resilient strap 22 mounted in a groove 23 in the member 19 and in block 21. 24 indicates an expansible coil spring engaging the wedge member and block 21., and together with the resilient strap 22 serving to hold the block 21 in engagement with the section 5 of the clamping member with the rail C, and permitting relative movement of rail C with rail A, the hook 8 and its pin connections 10 and 11 forming the pivot means'for said rail C. Vfedge member 18 is provided with a lateral projection 25 through which is secured a rod 26 that engages through a longitudinal opening 27 in the rail support, the end of said rod being threaded as shown at 28 to receive a clamping nut 29 to hold the wedge member 18 in clamping position. 80 and 31 are an vils on the ends of the wedge member 18 to sustain striking blows of hammers or other tools for driving the wedge member into and out of position.

What is claimed is 1. A rail oint support, comprising in combination with a fixed rail and a relatively pivoted ail, a rail chair having means engaging one side of the fixed rail and the correspond ing side of the pivoted rail in one of its positions, a clamping member for the opposite sides of said rails, said clamping member consisting of pivotally engaged sections, said sections engaging the fixed rail and the pivoted rail respectively, a wedge member holding the section in engagement with the fixed rail, and a spring actuated member engaging the other section and holding it engaged with the pivoted rail.

2. A rail oint support, comprising in combination with a fixed rail and a relatively pivoted rail, a rail chair supporting the meeting ends of said rails and provided with means engaging one side of the fixed rail and the corresponding side of the pivoted rail in one of its positions, a clamping member for the opposite sides of said rails, said clamping member consisting of pivotally engaged sections engaging the fixed rail and the pivoted rail respectively and pivotally mounting the pivoted rail, a Wedge member clamping in position the section engaged with the fixed rail, said wedge member having a recess therein, a

member mounted in said recess and engaging the other section of the clamping member, a

resilient band hinging said member to the Wedge member, and a spring urging the member into clamping relation with the movable clamping section.

3. A rail oint support comprising a chair having means to engage one of the sides of the meeting ends of railroad rails, one of said rails being an adjustable switch point, a clamping member for the opposite sides of said rails, said clamping member having pivotally engaged sections, and a wedge member engaging said clamping member, said Wedge member having a rigid portion engaging one section of the clamping member,.and a spring actuated clement engaging the other of said sections.

4. A rail joint support, comprising a chair having means to engage one of the sides 01 the meeting ends of railroad rails, one of said rails being a pivoted switch point, a clamping member for the opposite sides of said rails, said clamping member consisting of separable sections, means to pivotally connect said sections for relative movement, and a wedge member engaging said clamping member, said Wedge member having a rigid portion engaging one section of the clamping mem her, a movable member carried by said Wedge member and engaging the other section of the clamping member, and a spring tongue connecting the Wedge member and the movable member.

In testimony whereof I affix my signature.
